Does anyone have experience with https://lucia-auth.com https://lucia-auth.com ? OP says that it's deprecated, but it seems like it just changed from a library to a short guide on how to implement auth yourself. I'm planning to migrate our authentication and session management from auth0 to this to save costs and make things simpler.
